UNITED STATES JOHN F. MOONEY, OF WALLA WALLA, WASHINGTON.

LOADING MECHANISM.

Application filed May 16, 1923. Serial No. 639,232.

To all whom it may concern:

Be it known that 1, JOHN F. MooNnY; a citizen of the United States, residing at Walla /Valla, in the county of l/Valla lValla and State of lVashington, have invented certain new and useful Improvements in Loading Mechanisms, of which thefollowing is a specification.

This invention relates to loading mechanisms and has as one of its objects to provide a means for loading trucks and the like that will eliminate at least one handling of the material to be loaded.

Another object of the invention is to provide a means for loading trucks whereby two or more racks can be used and exchanged without confusion.

A further object of the invention is to provide a means for loading trucks Whereby two or more racks may be loaded and disposed of during a rush period.

l/Vith these and other objects in view reference is now had to the accompanying drawings in which- Fig. 1 is a plan view of the device;

Fig. 2 is a side elevation of the device with part broken away.

Fig. 3 shows constructional details on the line 33 of Fig. 2.

Fig. 4 is an end elevation of a loading jack.

Fig. 5 is a side elevation thereof; and

Fig. 6 shows a front elevation of trigger details.

Having reference to the drawings like numerals refer to like parts thruout the several views and the numeral (1) refers to a frame work consisting of vertical members (2), horizontal members (3), braces (4), and posts (5).

Substantially constructed with the frame work is a loading jack (6) consisting of a pair of independently operable jacks, each comprising a series of legs ('7) inclined, as shown, for strength, and braced by a cross bar (8), forming a frame therefor, to which is pivotally attached uprights (9).

The uprights are provided with notches (10) intheir upper ends for a purpose to be described, and these notches arepreferably shod with metal shoes (11) for pro tection purposes. The notches are formed in such a manner that a small lip (12) obtains on one side with a larger lip (18) on the other or rear side, and the purpose of ally operated by a lever handle (15) mountr ed in the frame (1) and connected to the uprights by a connection rod (16).

The lever handles being preferably placed forward of thejacks for convenience, so that the operatorwould not have to move from the seat 17 ofthe truck 18 to the rear of the jacks, obviously must be positioned to avoid interference with any moving body, such as a rack, to be explained, and is therefore offset by means of the bent bars 19 that extend from the bottom of the handle over to the connecting rod 16. The connecting rod is preferably of two pieces with one on each side of the uprights to provide an equal pull, or strain, on the bolts 20. H i i The lever handle is also preferably positioned on an inclinefor the same reason as are the uprights, as mentioned above, and to prevent a premature movement of the handle it is locked bya stirrup 21 hinged tothe post 22 in a manner to drop overthe end of the handle when at rest.

Thus the handle is maintained in a vertical position until ready for operation and by removing the stirrup the handle maybecome depressed aided by the load on the I upright-s.

The materials or objects, comprising the load are loaded into a rack 23 of any suitable design, the rack shownbeing one form Wood from a mill, or it might containboxes or other large stuff, and comprises sills 24, a floor 25, sockets 26, fastened suitably to the floor and carrying stakes 27, to hold the 7 load.

The sills are extended and are designed to rest in the notches 10 of the uprights during the loading period and by means of the lips 12 and 13 the rack is maintained in position against accidental dislodgment.

The sills are preferably extendedby means of a pair of irons 28 and these irons pivotally mount triggers 29- so shaped that the ends, being hooked, will engage aloop 3l adapted to contain long stuff such as slab and may be readily released therefrom by moving the locking means consisting of a yoke 32 pivotally attached to the sill in a manner that by swinging the yoke backward the outer end 33 of the trigger will be released. I

Upright posts 34 are provided as part of the frame 1 and these posts, with the post 22 carrying the stirrup 21, support a track 35 positioned above and extended beyond the jacks 6, in which is operably mounted an overheadv carrier 36 comprising a framework 37 mounted on wheels 38, which run in the track and provided with depending straps 39 terminating at their lower ends in loops 31, the loops being positioned for engagement with 'the triggers 29, as before mentioned, when the rack rests'on the up rights 9.

The overhead carrier, when above the jack, is obviously in operable contiguity with the jack, which it may now engage by means of the loops 31 of the straps 39 and the triggers 29.

A roller track 40 is mounted in the frame 1 and consists of a transversely positioned track 41 positioned adjacent to the front end of the device, a longitudinally positioned track 42 joining the first mentioned track, and a rear transversely positioned track, that terminates at one side of the jack.

By this means an empty rack may be deposited from the truck 18 onto the transverse track 41 and conveyed along the roller track 40 to the jack upon which, it being empty and relatively light in weight, it may be manually placed upon the jacks.

In use the rack is moved from the truck to the jack as above mentioned and when placed thereon is in a position for loading. For this purpose this end of the mechanism is placed as near as practicable to the source .of supply.

' The rack nowbeing loaded the truck may be backed between the jacks and the rack lowered onto the truck by unlocking the lever handle 15 and moving it forward. This motion throws the uprights 9 also forward carrying with them the rack which is prevented from premature dislodgment by the forward lip 12, while, as the motion continues, the rear lip 13 presses against the sill 24 and forces it free from the notch to rest'on the truck. 7

, To prevent a congestion two racks are desired for advantageous use, and with one rack loaded, and with no truck available on which to load it, this rack is engaged to the overhead carrier by the triggers 29 and straps 39, then the jack is lowered to release the rack which is then moved forward on the track 35Vand another rack substituted on the ack.

The truck now backs under the loaded and suspended rack and the rack is deposited will total a corresponding number to that accommodated by the roller track,

Hence, while the device is not exceptionally large it has ample capacity, and whether handling hay, grain in sacks, lumber or slabwood, its efficiency in actual test, is unquestioned.

Having thus described my invention, I claim- 1. In a loading mechanism, a loading jack, an elevated carrier positioned in operable contiguity with said jack, and a roller track positioned adjacent to and in operable contiguity with said jack.

2. In a loading mechanism, a loading jack, a rack, designed for support by said jack, an overhead'carrier positioned in operable conti'guity with said jack, and engageable with said rack, and a roller track positioned adjacent to and in operable contiguity with said jack.

3. In a loading mechanism, a loading jack provided with movable'uprights, means to operate said uprights, a rack provided with extended sills to rest on said uprights, triggers pivotally mounted in the ends of said sills, an overhead carrier operably positioned above said jack and provided with depending straps engageable with said triggers, and a roller track positioned in operable contiguity with said jack.

4;. In a loading mechanism, a jack consisting of a frame, and uprights pivotally mounted in said frame, a lever handle pivotally mounted in said frame to operate said uprights, a rack, said rack being provided with extended sills designed to rest on said uprights, triggers pivotally mounted in the ends of said sills, means for lock ing said triggers, a track positioned above said jack, an overhead carrier operably mounted on said track, and provided with depending straps for engagement with said triggers, and means to convey the rack to said jack.

5. In a loading mechanism, a jack, said 9 gers pivotally mounted in the ends of said sills, means for looking said triggers, said means comprising a yoke pivotally mounted on said sills and positioned swingingly about the ends of said triggers, a track positioned above said jack and extended be yond said jack, an overhead carrier operably mounted in said track and provided with depending straps terminating in loops, said loops being positioned for engagement with said triggers when the rack rests on the uprights, and means to convey the rack to said jack.

6. In a loading mechanism, a jack comprising a frame, uprights pivotally mounted in the frame and provided with notches in their upper ends, and said uprights normally positioned to incline forward, a lever handle pivotally mounted in said frame and operably connected to said uprights, means to lock said lever handle in a corresponding normal position, a rack provided with extended sills designed to rest in the notches of said uprights, said sills provided With triggers, means to look said triggers, a track positioned above said j aek and extended beyond said jack, an overhead carrier operably mounted in said track and provided With depending straps terminating in loops, said loops being positioned for engagement with said triggers, and roller track positioned in operable oontiguity With said jack to convey the rack to said jack.

In testimony whereof I fifl'lX my signature.

JOHN F. MOONEY.
